- Abstract
ABSTRACT Engineering plastics provide superior performance to ordinary plastics for wide range of the use. For polymer materials, dynamic stress and strain rate may be major factors to be considered when the strength is evaluated. Recently, high-speed tensile test is being recognized as a standard testing method to confirm the strength under dynamic loads. In this study, therefore, high-speed tensile test is analysed by the finite element method; then, the maximum dynamic stress and strain rate are discussed with varying the tensile speed and maximum forced displacement. The maximum strain rate increases with increasing the tensile speed u/ t, but the strain rate concentration factor
